iPhone 4 logic board replacement


I got an iPhone 4 and i'm having problems with the mic. I took the phone to a service shop and they told me that the problem is with the logic board and that it can't be fixed. In fact they told me that the logic board was warped! Is there a way to replace the logic board? would it cause more problems if replaced? And where can i find one and be sure that it's going to work?

Thank you all

Answer this question I have this problem too

Is this a good question?

i found the solution, there is a service center that fixes logic boards. After searching this a little bit more i found that this audio error is very common on iPhone 4 and it has to do with audio integrated circuit. There are two ways to solve this. Either you give it to service and they reattach the original circuit or replacing it with a new one or you can do this.. The first option costs 115 euros to fix it..

I have limited knowledge, but the Logic board is the main motherboard which will carry all the carrier settings etc, so replacing that might be a problem.

You might be able to find one on ebay or something similar where iphones are being sold for parts.......
